Having completed the Auto Deploy installation procedure, let's walk through the different modes you can use to configure vSphere Auto Deploy. There are three possible installation types you can use:

• Stateless: The ESXi image is not technically installed, but it is loaded directly into the host's memory as it boots.
• Stateless caching: The image is cached on the local disk, remote disk, or USB. If the Auto Deploy server is not available, the host boots from the local cache.
• Stateful: The image is cached on the local disk, remote disk, or USB. As compared to stateless caching, the boot order is inverted; the host boots first from local disk then from the network.

Let's have a look at the different procedures to configure Auto Deploy installations.
